Active clinical trials for "Myocardial Infarction"

The concentration of troponins in plasma is used for diagnosing acute myocardial infarction. Different types of heart-specific troponins can be measured and with different analytical methods. The primary aim of this study is to evaluate the diagnostic characteristics of a new analytical method for measuring troponin I in diagnosing acute myocardial infarction.

Type 2 myocardial infarction has been reported in the Universal Definition of Myocardial Infarction for more than 10 years and most studies resulted in a high mortality rate. However, little to nothing is known for both criteria to define myocardial oxygenation imbalance threshold and the outcome of these patients presenting with myocardial oxygenation imbalance. The aim of this study is to compare the outcome at 6 months for patients admitted in the emergency department with a myocardial oxygenation imbalance, depending on whether a type 2 myocardial infarction occured or not.

In late December 2019, an emerging disease due to a novel coronavirus (named SARS-CoV-2) rapidly spread in China and outside. France is currently facing the COVID-19 wave with more than 131 863 confirmed cases and almost 25 201 deaths. Systems of care have been reorganized in an effort to preserve hospital bed capacity, resources, and avoid exposure of patients to the hospital environment where COVID-19 may be more prevalent. Therefore, elective procedures of catheterization and programmed hospitalizations have been delayed. However, a significant proportion of procedures within the catheterization laboratory such as ST-elevation myocardial infarction (STEMI), non ST elevation myocardial infarction or unstable angina are mandatory and cannot be postponed. Surprisingly, invasive cardiologist noticed a drop in STEMI volume without reliable data to confirm this impression. Furthermore, a recent single center report in Hong Kong pointed out longer delays of taking care when compared to patients with STEMI treated with percutaneous intervention the previous year. These data are at major concern because delay in seeking care or not seeking care could have detrimental impact on outcomes.

This is a national multi-center, prospective surveillance study in patients with suspected acute coronary syndrome. Eligible patients must present to one of the participating Emergency Departments within 24 hours from the time of symptom onset. Approximately 2000 patients >18 and <85 years of age are planned to be enrolled. Upon enrollment in the Emergency Department, a venous blood sample will be obtained from each patient for analysis. The patient's diagnostic work-up, treatment and disposition will continue per the standards of the treating institution. Results will be recorded for ECGs, any cardiac biomarkers measured at the site and any follow-up cardiac objective tests performed for evidence of coronary artery disease and/or myocardial damage (exercise treadmill, coronary angiography, cardiac thallium or technetium scintigraphy, etc). The Principal Investigator at each site will evaluate the results of the diagnostic cardiac tests performed for that patient to determine whether each patient enrolled at their site has a final diagnosis of ACS. The status of each patient will also be assessed at 1 month and 6 months after enrollment for intercurrent Major Adverse Cardiac Events (MACE), including myocardial infarction, cardiac revascularization and death.

Cardiac-enriched micro-RNAs (miRNAs), micro RNA 208b and 133a(MiR-208b, MiR-133a)) corresponds to the health and disorders of the cardiovascular system. An intron of the cardiac myosin heavy chain gene MYH7 encodes miR-208b. It is found on chromosome 14 in humans. Identify new diagnostic biomarkers based on miRNAs, researchers examine the expression of miR-133a and 208b at various time points (04 hours, 08 hours, 12 hours, 24 hours, 48 hours) following the development of the infarct and compared it to the traditional myocardial infarction biomarkers cardiac troponine (cTnl) and Creatine kinase-MB (CK-MB).

The treatment of acute myocardial infarction (MI) in Poland is at the level of standardized European care. However, the first months after MI are crucial from the perspective of patient's prognosis. It is extremely important to take care of all cardiovascular risk factors. Mobile application (afterAMI) supported by web system is a novel telemedical tool created to support patient and physician during the process of cardiac rehabilitation. The application has educational model with focus on cardiovascular risk factors and lifestyle after MI. Moreover, there is a module to control vital signs like blood pressure, heart rate, weight and many others. Additionally, application will send reminders for better drug adherence. 100 patients will be recruited to take part in the study. All of which will be hospitalized at the 1st Department and Clinic of Cardiology because of the MI. The aim of the project is to study the impact of application-supported model of care with comparison to standard care. At the end of the study cardiovascular risk factors control will be analysed, as well as rehospitalizations, patient's knowledge regarding risk factors, return to work and quality of life. This will be a prospective, open-label, randomized, single-centre study. All 100 patients will be observed 6 months after discharge from the hospital. End points will be assessed during control visit 1- and 6-months after inclusion into the study. This project is an example of a telemedicine solution application into everyday practice, which is consistent with multiple international cardiac societies.

This is a GWAS study that aims to identify possible candidate genes associate to heart attack by exploring single nucleotide polymorphism (SNP) in a group of heart attack, in the Kazakh population. The investigators hypothesize that the careful phenotyping of the subject sand matching with increase the power to find SNP significantly associate with heart attack

The Covid-19 pandemic and its health and societal consequences raise fears of a deterioration in the management of non-Covid-19 pathologies, particularly those requiring rapid treatment. These fears relate in particular to strokes and acute myocardial infarctions (AMI), the two most frequent diseases, for which emergency treatment is a major factor in the vital and functional prognosis of patients. They are based on activity data from the emergency services, which have shown a sharp drop in admissions for AMI and strokes at the start of the pandemic. This drop is interpreted as being partly linked to a tendency for patients to delay or even give up care, which may be explained by fear of contamination, the desire not to solicit already overworked healthcare professionals and overload in emergency structures. In addition, studies have shown that the time required to treat AMI during the pandemic phase in China has been extended due to the new organizations set up in healthcare institutions in connection with this major health event. In addition, certain inequalities in access to care, already identified during the non- pandemic period among AMI and stroke patients, are likely to be accentuated by the new healthcare organizations set up during the pandemic period. The investigators are interested in the impact of changes in healthcare utilization and reorganization within hospitals, related to the Covid-19 pandemic, on the quality of the care pathway for stroke and AMI patients in the Aquitaine region. The investigators also study the role of the socio-demographic, socio-economic and geographical characteristics of these patients as factors of inequality of access to care during this period. The project is based on data collected within the Aquitaine Cardio-Neuro-Vascular Registries (CNV), an exhaustive cohort of stroke and AMI patients treated by a health care institution in Aquitaine. They are an excellent tool for describing the care pathway and outcomes of these patients, from the onset of symptoms to the end of the acute episode. An additional collection is planned to collect all the organizations and activities set up within the hospitals in Aquitaine. The study period, from January 2019 to August 2020, provides sufficient time before lockdown and after the date of the end of lockdown, to analyze trends in the quality of pathways, according to the various reorganizations of the health system and changes in the use of care linked to the management of the Covid-19 pandemic. The project identifies the reorganizations with the most striking consequences on the quality of care for patients suffering from non Covid-19 pathologies. It analyzes the changes in the behaviour of patients and their family and caregivers in their use of care during the Covid-19 pandemic and their impact on the care pathways and results. It contributes to the policy of reducing inequalities in access to care and to the definition of a health strategy in the event of a major health crisis.

A prospective non-interventional study aimed to evaluate the immediate and long-term outcomes in patients with left ventricular aneurysm after transmural myocardial infarction. A registry of patients with transmural myocardial infarction admitted to the Emergency Department of Cardiology will be created. The registry will include all consecutive hospitalized patients from from January 1, 2021 to December 31, 2021 who meet the inclusion criteria Based on this registry, patients will be divided into groups : patients with left ventricular aneurysm and patients without aneurysm, patients with left ventricular thrombosis and patients without thrombosis. Patients will be contacted in 3 and 12 months. Surviving patients will be invited to appointment for an ECG, echocardiography and survey. The cardiovascular events during this period will be recorded. The factors determining the prognosis of patients and their concomitant diseases, immediate and long-term prognoses, therapeutic measures and drug therapy at the hospital and outpatient stages, and patients ' adherence to therapy will be analyzed.

This is an observational study based on secondary data extracted from multiple register-based data sources in the US and Europe (Sweden, United Kingdom, Italy, Germany). The study will include patients initiating treatment with ticagrelor 60 mg after a myocardial infarction in real-world clinical practice, and describe their patient characteristics and duration of treatment. If the a priori threshold of 5,000 person-years on treatment with ticagrelor 60 mg is met, outcome events (bleeding and cardiovascular events) will also be analysed and described.
